Although I have the book C++-gui-programming-with-qt-4-2nd edition but I think starting Qt (Open Source) here in this website can be simpler, nicer, completer and updater. I have been suggested three links:

http://qt-project.org/doc/qt-5/gettingstartedqt.html
http://qt-project.org/wiki/Qt_for_beginners_Hello_World
http://qt-project.org/doc/qt-5/tutorials-addressbook.html

And myself could find another:
http://qt-project.org/doc/qt-5/index.html

Which one do you suggest me? Please keep in mind that I'm very novice and want to get a link and don't unhand it until end.
Is there such a link here?

Thanks in advance.
